Rhino Bridge helps you move crypto from one chain to another from your phone without turning a simple transfer into a guessing game. If you want to bridge assets across supported networks like Ethereum, Arbitrum, Optimism, Base, zkSync, Polygon, or Starknet, Rhino Bridge gives you a mobile-friendly way to handle the route while keeping control through your own wallet.
The mobile problem is usually the small screen, the app switching, and the easy-to-miss details: wrong chain, wrong token, not enough gas, or a fake front-end opened from a bad link.
This guide shows what to prepare, what to check before approval, and how to avoid expensive mistakes.
Before you start, have these ready:
Open rhino.fi through your wallet's in-app browser or through your mobile browser, then connect your wallet. MetaMask mobile is a common option because the browser and approval prompts stay close together.
Check that you are using the correct front-end before connecting. Mobile browsers often hide full URLs, and search results or direct messages can lead to unofficial pages.
Connecting your wallet does not move funds. It lets the bridge read your public address and prepare a transaction for review.
Connect the wallet account that holds the funds. If your wallet has multiple accounts, confirm the active account before moving on.
Then check the network shown in your wallet. If your funds are on Arbitrum, Arbitrum is your source chain. If they are on Ethereum, Ethereum is your source chain.
